Claims. (c 5- 90) This invention relates to improvements in 7 invalidand hospital. beds.

It is an object of. the. present. invention. to provide an economical,efficient and. practical invalid or hospital bed. havinginstrumentalities for permitting the patient to. perform hiseliminations without generally disturbing his comforts or his restingposition.

A further object of the invention, is to provide a hospital bed with amattress having a central portion which is readily, conveniently andmechanically removable for substitution by a bed pan mechanicallyoperable for placement thereof for said central portion, when necessary,for use by the patient. I

A further object of the invention is to provide a hospital bedincorporating mechanical fea-- tures for sanitarily introducing into thebed mattress a bed pan for use by the. patient when, desired.

Further objects and advantages of the invention will. appear from thefollowing disclosures thereof together with the attached drawings which.illustrate certain forms. of embodiment thereof. These forms are shownforv the purpose of illustrating the invention since thesame have beenfound in practise to give satisfactory and reliable results, although itis to be understood that the various instrumentalities of which theinvention consists can be variously arranged and organized and that theinvention is not limited to the precise arrangement and organization: ofthe instrumentalities as herein shown and described.

Fig. 6 is an enlarged fragmentary detail sectiorr taken adjacentthecenter opening of a mattress embodying the invention in a modified form,with closure cushion in place.

Fig. "1 is a diagrammatic fragmentary enlarged sectional View adjacentthe center opening of a ther modified form with closure cushion inplace, the'parts not being shown in detail.

Fig; 8' is a sectional view of a bed pan with cushion ring employable inthe invention.

. Fig.9 is "a partial sectional View of the center 5 portion of the bedshown in Fig. 1-, the bed pan being. shown. inoperative position.

In the drawings which embody a preferred form of the invention, the bedframe [5 is provided with a conventional bed spring l6 having aflatplate ll made preferably'of metal secured at It to the two members l9and 20 of bed spring l6; Atrthe center of plate l! is a preferablycircular opening 21'. A closure or cover 22 is hingedly securedto plateIT at 23 and is held in closed position by a latch 24, which isfulcrumed' at 25 to plate l1 and connected to an operating bar or lever26 at 21. The latch 24 is provided with a tapered projection 28 to aidin gripping the cover when almost closed and forcing the same intoclosedposition.

Cover 22 is operated for swinging movement by means of lever 40' securedto the extension M of the hinge pin 23'. In lieu of a lever 40, a wheel(notshown), may be employed to rotate hinge pin 23. 1

A resilientelement or mattress 3!] has a preferably' circular opening3!. The wall defining opening 3| is lined and the portion of mattress3D;adjacent opening 31 is covered with rubberized or other waterproof ornon-absorbent material 32. "Stitches- 3 3; secure the material 32 tomattress 3ll.- An upwardly-extending ring or flange 29 which ispreferably made apartofcover 22 isused to secure in position a resilientelement shelf or support 5| :1 which may be operated up- 7' wardly anddownwardly by a lever 52 connected thereto. and fulcrumed at 51 ongusset 52', the latter being secured to frame member 58' by rivets orother suitable means R. Frame members', 58, 58' may be secured to plateIT. A. bar 59 which may form part of frame member 58 has a vertical slot60- which limits" the up and down movement of shelf 5m. Shelf 51a, isprovided with a downwardly-projecting member 5llb which forms at itsvextreme end the arm Me having a pin 5ld made to slide in the slot 5Ie oflever 52. A latch 53 secured to the upper part of frame member 58 keepsthe lever 52 in its upper position. Lever 52 when raised places bed panor chamber 50 in utilizable position as shown in Fig. 9. To place thebed pan in this latter position, latch rod 26 is first pulled outward torelease the latch 24; lever 40 is then swung downwardly thus swinging inthe same direction cover 22 carrying cushion 34 all as shown in Fig. 9.Bed pan 50 is placed on shelf 5|a. and lever 52 is then swung upwardlyuntil engaging with latch 53. This places the bed pan 5!! in opening 3|.Thus bed pan 5!] replaces cushion 34.

As indicated particularly in Fig. 8, the bed pan 50 is preferablycovered with a cushion ring 5| having the depending flange 5|. This'ringcomprises the resilient filling 52 covered by a rub berized or other.moisture proof or non-absorbing fabric 53, there being further provideda remov-' able fabric cover 54, which may be secured to the bed pan 50by means of cords or other flexible elements 55 tied to hooks or loops56 of the bed pan.

Fig. 6 shows the mattress in a modified form. This mattress has a bottomopening 62 communicating with a reduced top opening 63 formed by thecushion ring 64 secured to the mattress body 30. Within these openingsis normally positioned a cushion 34' of similar construction to that ofcushion 34. The cushion 34' is drumshaped and of a diameter to fit thereduced opening 63, leaving an annular space 65 surrounding cushion 34'.Cushion 34' is covered with suitable moisture-proof material 35, overwhich is placed a removable flexible cover 36 made of suitable fabricmaterial and which may be held in place by any suitable means such as,for example, a string-{or cord 36" or by snap fasteners (not shown). InFig. '7 which is merely diagrammatic, the cushion 34" is shaped tosubstantially snugly fit both openings 62" and 63". In this case theflange 64" forms an integral portion of the mattress 30". When using themattress forms shown in Figs. 6 and 7, a bed pan without the padding 5|is preferably employed.

Operation of the device is as follows:

Mattress 3G is covered with regulation bed sheet having a centralopening registering with the opening 3] in the mattress. Cushion 35 isnormally in position shown in Fig. 1. This cushion 34 is covered withmaterial 35 of similar character as that of the bed sheet (not shown)thereby providing a uniform surface similar to the conventional sick-bedmattress. The shelf 5la. in this case will be in its lowered position asindicated in Fig. 9. If the patient desires to eliminate, the cushion 34is swung downwardly by means of handle 40 as shown in Fig. 9, the bedpan 50is placed on shelf 5m and the same is then raised until itcompletely fills the opening 3|. After the elimination has beencompleted by the patient, the bed pan 50 is lowered on its shelf 5Ia forremoval and the hinged cover 22 having the cushion 34 is swung upwardand again held in place by means of the latch 24. These operations havebeen performed without in any way disturbing the patients position whichin many forms of diseases, abdominal operations and critical injuries isvery undesirable and painful.
